摘要: 为了筛选富硒稳产高效型小麦品种和定位适宜种植优质强筋小麦的区域。选取石家庄藁城区、邢台宁晋县、邯郸馆陶县3个试验点,7个优质和5个高产冬小麦品种,收获后测定籽粒硒含量,比较了相同小麦品种不同地区间和同一地点不同小麦品种间籽粒硒含量的差异,分析产量与籽粒硒含量的关系。结果表明:不同地点间小麦籽粒硒含量的平均值以藁城最高为0.177 mg/kg,总体达到富硒小麦的标准,宁晋次之为0.084 mg/kg,馆陶最低为0.04 mg/kg;同一地点优质强筋小麦籽粒硒含量平均值均小于中筋小麦,藁城优质强筋小麦籽粒硒含量平均值较中筋小麦减少37.6%,宁晋减少26.7%,馆陶减少15.6%;土壤中硒含量与小麦籽粒硒含量呈正相关关系(R=0.972),差异不显著(P=0.152>0.05)。中筋小麦品种衡4444、济麦22及高产品种石麦22、邢麦13和婴泊700的籽粒硒含量均达到0.2 mg/kg以上,可作为适宜本地区的富硒小麦品种。

关键词: 冬小麦, 不同地点, 不同品种, 籽粒硒含量

Abstract: The aim of this study was to screen the selenium-enriched wheat varieties with stable yield, high efficiency, and to locate the suitable area for planting high quality and strong gluten wheat.The study selects 3 test sites including Gaocheng district of Shijiazhuang, Ningjin county of Xingtai and Guantao county of Handan, as well as 7 high quality winter wheat varieties and 5 high yield winter wheat varieties, the selenium content in grains was measured after harvest, and the differences of selenium content in grains between different regions of the same variety and between different wheat varieties in the same location were compared, the relationship between grain yield and grain selenium content was analyzed. The results showed that the highest mean value of selenium content in wheat grains was 0.177 mg/kg in Gaocheng which reached the standard of selenium-enriched wheat, followed by 0.084 mg/kg in Ningjin, and the lowest value was 0.04 mg/kg in Guantao; the mean selenium content of high quality strong gluten wheat was lower than that of medium gluten wheat in the same place, the mean grain selenium content of high quality strong gluten wheat decreased by 37.6% than that of medium gluten wheat in Gaocheng, Ningjin decreased by 26.7% and Guantao decreased by 15.6%. There was a positive correlation(R=0.972) between soil selenium content and grain selenium content of wheat, but the difference was not significant(P=0.152>0.05). The grain selenium content of middle gluten wheat varieties H4444, JM22, SM22, XM13 and YB700 reached more than 0.2 mg/kg, which can be used as selenium-rich wheat varieties in this region.
